If you want a body like Whitney, eat more. "I get a lot of people who want to build their glutes, but they also want to be on a diet," Johns told Muscle and Fitness. "You can't really build that muscle on a calorie deficit." Therefore, she eats more, not less. "As long as you are doing a clean-calorie surplus, you have to remember you are 'doing it for the glutes!" Johns says.

"I really encourage my clients to track their macros," Whitney told Muscle and Fitness. "Even if that's just a couple of times per week because meal serving sizes are so deceiving. I hate tracking macros too, but if you can make yourself do it, you will find out if your protein intake is on point, or if your calorific intake is on track, and then you will know you are getting somewhere."

"My love of fitness started when I was 16 years old. I grew up suffering from severe migraines, chronic pain, mental health, and gut health issues. I got fed up feeling poorly all the time, so I took matters into my own hands and started searching for solutions," Whitney told Fitness Gurls. "I spent years researching and self-testing. It became clear that to heal my body, I had to make nutrition and lifestyle choices that were going to improve my internal health, not just my outer physique."

Whitney told Dumb Blonde that she eats more paleo style because that's how she feels good. She also abides by the 80/20 rule with veggies, lean protein, and healthy fats. On occasion, she will cheat. "If you can do just one cheat meal instead of a cheat day or week, you will fulfill those cravings without derailing your whole diet," she added. df44d9eab23ea271ddde7545ae2c09ec

Whitney stays away from dairy for the most part. "When it comes to my diet that works best for my body: I try to stay dairy free, higher fat and lower carbs… but sometimes that Ice Cream craving is just the most," she said via Greatestphysiques.
